                        download. For example, if you tap    when the video footage is played to 00:00:30,
                        the segment from 00:00:20 to 00:02:30 will be selected. Note:

                                seconds. For example, if you start downloading from the very
                                beginning of the video footage, the selected segment will be from
                                00:00:00 to 00:02:10.
